DIFFERENCE BETWEEN REAL GAS AND IDEAL GAS (IN POINTS)
Ideal gas | Real gas |
Molecules have negligible volume in comparison to the Total volume of the gas. | Volume of molecules is very small but not negligible in comparison to the total volume of the gas. |
Collision between two molecule is elastic that is energy and momentum during the collision remain conserved | Collisions between molecules in real gas are not perfectly elastic. |
There is no mutual force of attraction or repulsion between the molecules of ideal gas therefore ideal gas can't be liquefied. | There is force of attraction between the molecules of real gas therefore can be liquefied at high pressure and low temperature. |
Ideal gas obeys PV = nRT (ideal gas equation ) | Real gas obeys vander walls equation.
|
This gas follows all gas laws at all temperature and pressure conditions. | This gas does not follow gas laws at all temperature and pressure conditions. However, a real gas behaves ideally at high temperature and low pressure conditions. |
